The Goodman B1376853 Motor Mount Arm is a genuine OEM condenser fan motor bracket engineered as an exact-fit replacement for the Goodman APH1430H41DD heat pump. This stamped-steel arm supports the condenser fan motor in the top of the outdoor unit, holding it centered over the coil and rigidly aligned with the fan blade. A bent, rusted, or fatigued mount arm causes motor vibration, blade rub, and premature bearing wear — replacing it restores quiet, balanced operation.
The genuine Goodman arm matches the original hole pattern, arm length, and offset exactly, so the motor and blade seat at the correct height and clearance. Generic or fabricated brackets rarely match the geometry and can leave the blade rubbing the shroud or the motor off-center. At this price point, there is no reason not to use the OEM part.
Rating: Easy (2/5). Replacement takes about 20–30 minutes. Disconnect power, remove the fan grille/top panel, transfer the motor to the new arm, and reinstall. Basic hand tools are all that is needed, and no refrigerant work is involved.
